      The Bug:

      Sculk sensors are not activated upon chickens laying eggs.

      Steps to Reproduce:

      • Place down a sculk sensor.
      • Summon a chicken that will immediately lay an egg nearby.
      • /summon minecraft:chicken ~ ~ ~ {NoAI:1b,EggLayTime:1}
      • Take note as to whether or not sculk sensors are activated upon chickens laying eggs.

      Observed Behavior:

      Sculk sensors are not activated upon chickens laying eggs.

      Expected Behavior:

      Sculk sensors would be activated upon chickens laying eggs.

      Code Analysis:

      Code analysis by Avoma can be found below.

      The following is based on a decompiled version of Minecraft 1.18.2 using MCP-Reborn.

      public class Chicken extends Animal {
         public void aiStep() {
            if (!this.level.isClientSide && this.isAlive() && !this.isBaby() && !this.isChickenJockey() && --this.eggTime <= 0) {
               this.playSound(SoundEvents.CHICKEN_EGG, 1.0F, (this.random.nextFloat() - this.random.nextFloat()) * 0.2F + 1.0F);
               this.eggTime = this.random.nextInt(6000) + 6000;

      If we look at the above class, we can see that chickens laying eggs simply isn't registered as a game event as the gameEvent() method is never called, thus not detecting this action as a vibration.

      Potential Fix:

      Simply calling the gameEvent() method where appropriate within this piece of code should resolve this problem. I feel as if a new game event tag would be expected to be used here as none of the currently existing ones seem to fit this action accordingly.
